dominant trait Dominant trait. A genetic trait in which one copy of the gene is sufficient to yield an outward display of the trait; dominant genes mask the presence of recessive genes; dominant traits can be inherited from a single parent.Mentioned in: Cutis Laxa, Polydactyly and Syndactyly, Pseudoxanthoma Elasticum.n inherited characteristic that is determined by a dominant allele. Polydactyly is an example of a dominant trait; individuals with either one or two copies of the polydactyly allele have extra fingers or toes. (dom'i-nănt trāt).

What is the definition of a dominant trait in biology? When binary traits are available, they become classified as Dominant or recessive. A dominant trait is a trait the is evident by the appearance of the organism. A recessive trait is a trait the is present but is not evident in the appearance of the organism. Dark hair is a dominant trait to a recessive light hair trait. Two brunettes may have a chance of having a blonde child due to the fact that either of them may carry the blonde haired gene and not show it.

-  …   A dominant trait is the expressed result of an organism having  either one dominant and one recessive gene for that trait, OR two  dominant genes for that trait. For example, brown eye color is  normally dominant over blue.    A recessive trait is the expressed result of having two recessive  genes.ominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait … has both genes to be homozygous recessive. in fact trait is controlled by the form of genes.

Dominance (genetics) Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive.For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.he first allele is dominant and the second allele is recessive. For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.

dominant noun A phenotype expressed when a particular gene is present in a cell, regardless of whether the allelic set contains 2 different forms of expression; the allele with the masked phenotype is termed recessive. Autosomal dominant disorders. Achondroplasia, familial hypercholesterolemia, Huntington’s disease.

Homozygous Dominant: Definition & Example Homozygous dominant is a genotype that consists of two dominant alleles for a gene. Although a homozygous dominant cat might have the same phenotype, or appearance, as a heterozygous one, the difference is that the homozygous dominant individual will 'breed true'.f a cat (or a person, or a pea plant) has two dominant alleles of a certain gene, we say it is homozygous dominant for that particular trait.

- Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene.(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes).A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes).Examples of dominant disorders include: 1  Achondroplasia (a common form of dwarfism with short arms and legs),ominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene.

Simple Dominance: Definition & Concept We get one chromosome from our mother and one from our father. Simple dominance occurs when an inherited trait is coded for by a single gene and that gene has two versions, or alleles: the dominant version and the recessive version.The dominant allele of the gene hides the presence of the recessive allele.ne human trait that's expressed through simple dominance is the ability to taste the bitter chemical PTC, which is expressed by a single gene that codes for a taste receptor on the tongue.

Dominant Inheritance Dominant Inheritance. Dominant Inheritance. When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present. A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.

dominant lethal trait dom·i·nant le·thal trait. trait, expressed in the phenotype if present in the genotype, which precludes having descendants. All such cases are necessarily sporadic and must represent new mutations as the usual methods of classic genetics provide no means of demonstrating any genetic component whatsoever, except for tenuous arguments such as advanced paternal age.

- Definition. Autosomal dominant is one of several ways that a trait or disorder can be passed down through families. If a disease is autosomal dominant, it means you only need to get the abnormal gene from one parent in order for you to inherit the disease. One of the parents may often have the disease.

- Making the world better, one answer at a time. Source traits describe the personality dimension or type of personality which underlies a person's trait personality which differs from one another. Surface traits are identified or projected by the individual according to the situation and environment.ominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive! Edit.

Understanding The Duties and Responsibilities of a Trustee Married couples who set up one trust together are co-grantors of their trust. Only the grantor(s) can make changes to his or her trust. The trustee manages the assets that are in the trust. Many people choose to be their own trustee and continue to manage their affairs for as long as they are able.

Dominant gene In genetics, the term dominant gene refers to the allele that causes a phenotype that is seen in a heterozygous genotype. Every person has two copies of every gene, one from mother and one from father. If a genetic trait is dominant, a person only needs to inherit one copy of the gene for the trait to be expressed. Dominance/recessiveness refers to phenotype, not genotype. Consider sickle cell anemia as an example. The sickle cell genotype is caused by a single base pair change in the beta-globin gene.

Dominant In genetics, the dominant pertains to the one that determines the phenotype of an organism. Its effects are readily recognized than the effects of the recessive. Usually, a dominant allele is symbolized with a capital letter and the recessive allele a small letter, for example: Hh (where H refers to the dominant allele while h to the recessive allele). In ecology, a dominant refers to an organism, such as an animal, dominating a social hierarchy and usually is the top predator with the greatest access to food resources, territory and mate. In neurology, a person may be left-brained or right brained depending on which side of his brain is dominant or frequently used.

What is a Dominant Trait? Top 10 facts about the world. A dominant trait is a genetic trait which will manifest when only one copy of the gene is present, overriding another inherited gene coding for a different version of the trait.By contrast, a recessive trait will only appear if an organism inherits a copy of the gene from both parents.n a simple example of the way in which dominant traits work, someone could have two parents who are heterozygous for brown and blue eyes. There is a 25% chance that the child will inherit the bb allele, making him or her blue-eyed.

Homozygous Dominant: Definition & Example Example of Homozygous Dominant. In cats, the agouti allele is dominant. It causes each hair in the cat's coat to have sections that are black and sections that are another color, such as gray. Tabby cats have the agouti allele, giving their fur a multicolored appearance.f a cat (or a person, or a pea plant) has two dominant alleles of a certain gene, we say it is homozygous dominant for that particular trait.
